WILLIAM A. CRAWFORD, OF DANVILLE, ILLINOIS.

FARM-GATE Specification of Letters Patent.

Patented. Dec. 31, 1907.

Application filed February 13,1907. Serial No. 357,203.

To all whom it may concern:

Be it known that 1, WILLIAM A. CRAW- FORD, a citizen of the United States, residin at Danville, in .the county of Vermilion an State of Illinois, have invented a new and useful Farm-Gate, of which the following is a specification.

This invention relates to gates and has for its object to provide a comparatively simple and me); ensive device of this character capable of being adjusted vertically to open and closed position and which may be operated from either side of the road-way.

A further object of the invention is to provide a gate which may be moved to open position when snow is banked or drifted on each side of the gate and which will positively engage its keeper when moved to closed osition. 1

A sti 1 further object of the invention is to generally improve this class of devices so as to increase their utility, durability and efliciency.

With these and other objects in View the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, and illustrated in the accompanying drawings, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

In the accompanying drawings forming a part of this specification: Figure 1 is a side elevation partly in section of a gate constructed in accordance with my invention showing in dotted lines the gate in elevated or open position. Fig. 2 is a top plan view of the gate showing the same in closed position. Fig. 3 is a vertical sectional view taken on the line 33 of Fig. 1. Fig. 4 is a side elevation of one of the lever supporting posts and its associated parts. Fig. 5 is a similar view illustrating a modified form of gate 0 erating lever.

Simi ar numerals of reference indicate corresponding parts in all of the figures of the drawings.

The improved device consists of the spaced gate posts 5 and 6 to one of which is bolted or otherwise rigidly secured horizontally disposed bars 7 carrying spaced inclined standards 8.

Pivotally mounted at 9 between the standards 8 are a lurality of spaced longitudinal rails or pane s 10 which constitute the gate proper, said panels being pivotally connected'by means of inclined battens 11 preferably arranged in pairs and dis osed one on each side of the longitudina rails or panels, as shown.

The free ends of the rails 10 preferably project beyond the adjacent batten 11 and are provided with curved or rounded terminals 12 adapted to engage a vertical recess 13 in the gate post 6, the latter constituting a keeper and serving to lock the gate against lateral movement when the gate is in closed position.

Bolted or otherwise rigidly secured to the upper end of the post 5 is a supporting block or bracket 14 on which is pivotally mounted a balancing lever 15 having one end thereof provided with spaced depending hangers 16 carrying an anti-friction roller 17 adapted to bear against the bottom of the adjacent longitudinal rail or panel 10.

Slidably mounted on one end of the lever 1.5 is a weight or counter balance 18 capable of being adjusted longitudinally of the lever thereby to balance the gate and permit the same to be readily moved to open and closed position, said weight being locked in adjusted position by means of a set screw 19 carried by the weight and adapted to enter any one of a plurality of openings 20 formed in the balancing lever 15, as shown.

The balancing lever is preferably reinforced and strengthened by the provision of a longitudinal truss rod 21 which engages suitable stay blocks 22 and is bolted or otherwise rigidly secured to the opposite ends of the balancinglever.

Disposed on opposite sides of the gate and preferably arranged at right angles thereto are lever supporting posts 23 and 24 in which is journaled a horizontally disposed rod or operating shaft 25. The rod 25 pierces the supporting bracket 14 and balancing lever 15 and is rigidly secured to the latter so that when the rod is rotated the balancing lever will be tilted vertically and thereby move the gate to open position. The rod 25 is eX- tended beyond the adjacent side walls of the posts 23 and 24 and keyed or otherwise rigidly secured to said rod are operating levers 26 carrying depending handles 27, the two being pivotally united by a link or loop 28 so as to cause the handles to hang in a vertical plane regardless of the position of the lever 26.

Secured to the rod 25 at the inner faces of the posts 23 and 24 are crank arms 29 which are pivotally connected through the medium of the links 30 with the levers 31, the latter being provided with depending operating handles 32 similar in construction to the handles 27. The levers 31 are pivotally mounted at 33 on laterally extending supporting brackets 34 carried by the posts 23 and 24. The lower ends of the brackets 34 are bolted or otherwise secured to the posts, as indicated at 35 while the upper ends of the brackets are extended laterally to form bearing plates 36 which are secured to and form housings for the upper ends of the lever supporting posts thereby to protect the latter from the action of the elements.

In order to elevate the gate it is merely v necessary to exert a downward pull on'the handle 32 which will tilt the lever 31 and through the medium of the crank arm 29 rotate the rod or shaft and-thus tilt the gate to the open position indicated by the dotted lines in Fig. 1 of the drawings. As the gate is tilted the roller travels over the lower face of the upper longitudinal rail or panel 11 of the gate and thus reduces friction between the parts and also forms a means-for guiding the gate in its upward movement. When the hand-piece 32 is. lowered the opposite hand-piece 27 will be moved upwardly so that by exerting a downward pull on the hand piece 27 the gate may be moved to closed position with the curved terminals of the longitudinal rails bearing against the side walls of the keeper thereby to prevent lateral movement of the gate.

The weight 18 serves to balance the gate and permit the same to be readily moved to open and closed position.

In Fig. 5 of the drawings there is illustrated a modified form of the invention in which one of the operating levers 26 is formed with a segmental rack 36 pivotally mounted on the supporting bracket 37 and adapted to engage the teeth on a gear wheel 38 carried by the operating shaft or rod 25, the construction being otherwise similar to that shown in Fig. 1 of the drawings.

From the foregoing description it is thought that the construction and operation of the device will be readily understood by those skilled in the art'and further description thereof is deemed unnecessary.

Having thus described the invention what is claimed is:

1. The combination with spaced gate posts, of a gate pivotally mounted for tilting movement between said posts and consisting of spaced longitudinal rails pivotally connected by inclined battens, a balancing lever pivotally mounted on one of the gate posts and having one end thereof deflected upwardly and provided with spaced perforations and its opposite endprovided with depending hangers, an anti-friction roller journaled in the hangers and bearing against the adjacent longitudinal rail of the gate, stayblocks extending vertically from the upper edge of the balancing lever near the opposite ends thereof, a truss rod bearing against the stay blocks and secured to the lever, a weight slidably mounted on the deflected end of the lever, a fastening device carried by the weight and adapted to engage the perforations in the operating lever for holding the weight in adjusted position, and means for tilting said lever thereby to raise and lower the gate.

2. The combination with spaced gate.

posts, of a gate pivotally mounted for vertical movement between said posts, auxiliary posts disposed one on each side of the gate, an operating shaft journaled in the auxiliary posts, a balancing lever rigidly secured to the operating shaft, and spaced operating levers secured to the opposite ends of the shaft and disposed at an angle to each other for moving the gate to open-and closed position.

3. The combination with spaced gate posts, of a gate pivotally mounted for vertical movement between the gate posts, auxiliary posts disposed one on each side of the gate, an operating shaft journaled in the auxiliary posts, a balancing lever rigidly secured to the shaft and operatively connected with the gate, brackets carried by the auxiliary posts, crank arms secured to the shaft at said brackets, levers pivotally mounted on the brackets, links forming a pivotal connection between the levers and crank arms, and auxiliary levers secured to the opposite ends of the shaft for raising and lowering the ate.

b 4. The combination with spaced gate posts one of which constitutes a keeper, a gate pivotally mounted for vertical movement between the gate posts and adapted to engage the keeper, a balancing lever mounted on one of the gate posts, auxiliary gate posts disposed on each side of the gate, an

operating shaft journaled in the auxiliary posts and piercing the balancing lever, said balancing lever being rigidly secured to the operating shaft and provided with a longitudinally adjustable counterweight, a hanger depending from one end of the balancing lever and provided with an antifriction roller adapted to bear against the gate, brackets secured to the auxiliary posts, operating levers pivotally mounted on the brackets, crank arms carried by the shaft, links forming a pivotal connection between the operating levers and crank arms, and auxiliary levers carried by the opposite ends of the shaft anddisposed at an angle to the first mentioned levers.
